EP worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless get for top quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, will make the EP worm gearbox the default choice for the industry. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide great torque with low swiftness gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Worm reduction gears features
A worm gear is a kind of interlocking gear composed of a worm shaft and worm wheel. The worm can be shaped such as a screw and the worm wheel is usually a kind of gear machined to own a tooth account with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that is fixed to ensure that it cannot rotate and for that reason progresses in the axial direction when the bolt is usually turned.
The design of a worm gear is considered through the relationship between the rack and spur gear on the middle plane of the worm wheel.
Substantial reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. Due to this, in a 1 speed reduction gears, the wheel could be manufactured therefore that it will be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic can help you layout the turning tranny direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). You’ll be able to switch the rotation path of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For example, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Physique 2) and, if attachment orientations are included, you’ll be able to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is definitely characteristic because the contact is certainly linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are really low. Because of this, this technology can be used to drive medical equipment, elevators and escalators, etc.

Key points when choosing a worm reduction gears
When choosing a worm reduction gears, the procedures for selecting the right gear are described in the manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care should be taken in essential areas such as selecting the strain index, calculating the overhang load and examining heat rated capacity from the manufacturer.
Cautions during use
When using a worm reduction gears, heat produced through the initial amount of use is large and running-in procedure at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key to sufficiently attaining the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to change the lubricating oil and also to change the lubricating oil from then on about 1 time each year according to the procedure manual furnished by the manufacturer.
The Worm Decrease Gear Box is provided by our company is of supreme quality. Our products are created through the use of premium quality materials and progress technology at our vendors end. They are widely used in a variety of sectors. Our products are often available at an extremely low market prices.

They succeeded in merging uncompromising quality with stateoftheart technology amd renown cost effectiveness.Absolute flexibility is given by the wide choice of several mounting options, shaft configurations and electric motor interface, all offered as regular. The helicalworm and the doubleworm version, with or without the torque limiter, also add up, creating a highly versatile drive system.
20 level C TO 80 degree C
The worm reduction gears come in two series: X and H.
The series X, featuring a worm and worm wheel set, comes in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell housing + coupling) offers great versatility to match a broad range of applications and provides higher efficiency compared to the compact brand XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features because series X with an extra plus: a spur gear pre-stage at the insight end provides higher efficiency and a good broader selection of ratios compared to the X series.
Body sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow output shaft is supplied as standard.
Broad range of possibilities:
second input, output flange, single or double extension output shaft, torque limiter with through cable connection, torque arm.
